Is there a reason that you are Not putting on Mass with a Long Ester Test.
Like Test C or E.
One of these should be your 1st Choice, as Long Esters are More Anabolic than Short Esters.
Due to the Length of time that they remain active in the Body.
Stacking Test C or E with EQ would be a good choice for Lean Mass.
But you still need a Good Diet and Training Regiment to go along with this............................. JP
P.S.
Your Current Stats would be Helpful.
Age/Height/Weight/approx. Body Fat Percent.
Years Training and Type of Training.
